Page 5: Device Description
Instruction Manual DM08 Device description The DM08 flow meter from PKP is a flow sensor without moving parts. The measurement is per- formed using magnetic induction. The DM08 is used for measuring or dosing water and electrically conductive fluids. The complete measuring instrument comprises the sensor and the related display electronics. -

DM08"). Take appropriate measures to ensure that the medium does not freeze. Only use the DM08 if it is in perfect condition. Damaged or faulty devices must be checked without delay and, if necessary, replaced. When fitting, connecting and removing the DM08 use only suitable, appropriate tools. -
Page 9: Construction And Function
Construction and function Construction The DM08 comprises a sensor and the display electronics. The sensor is used to measure fluid media. The display electrodes generate the coil current required for the magnetic field and pre- pares the induced voltage applied to the electrodes. -
Page 10: Measuring Principle
The magnetic inductive flow sensor operates on the inductive principle, i.e., a direct current is gen- erated by the movement of a conductor in a magnetic field: The measuring pipe of the DM08 is in a magnetic field (B). An electrically conductive medium (Q) passes through the pipe. -
Page 11: Installation Instructions Display Electronics
For the separate version, the minimum permissible conductivity of the medium is determined by the distance between the sensor and the display electronics. The maximum cable length to ensure accuracy is 200 m (p. 19 "Connecting cables"). - 10 - PKP Prozessmesstechnik • 09/2019... -

Page 14: Cathodic Protectives
General: The DM08 can always be installed at any point on the pipeline in the horizontal as well as in vertical sections. Ideally, the sensor should be installed in a pipeline with a sufficient straight run, both before and after the measuring point. - Page 15 It must be ensured, that the axes of the electrodes are running horizontally to avoid erro- neous measurements due to deposits or air bubbles on the electrodes. Also, note that in case of deviations from horizontal, the functioning of the Empty pipe de- tection (p. 9) is limited. - 14 - PKP Prozessmesstechnik • 09/2019...
- Page 16 Instruction Manual DM08 Installation in unfilled pipeline: If a pipeline is not always filled, or in case of an open channel (drainage), the sensor must be installed in a siphon. That means the flow tube cannot run dry and is always filled with measured medium.
